Hello,
in the Zabbix I'm responsible of, there are plenty of flapping "Zabbix agent is not available".
One thing I've saw is the latest data for impacted hosts : the last check time can be way over the configured interval for some items.
These items do not have a preprocessing at all. But they are passive.
The poller data collector is fine, in average it is below 3%.
The required server performance, new values per seconds is 5000.
I can't say it's related, because on another test instance with only 4 hosts, we have the same issue.
I can't find anything in the logs, but I would gladly provide one if needed, just let me know.
Do you have any ideas ?
Let me know if you need more insights.
Thank you in advance for four time and help.
